NASA’s New Horizon probe has confirmed the presence of frozen methane on which of these bodies?
NASA’s New Horizon probe has confirmed that there is frozen methane on Pluto’s surface. Methane was detected by a team of ground-based astronomers led by New Horizons team member Dale Cruikshank of NASA’s Ames Research Center, Mountain View, California. Methane is an odourless, colourless gas that is present underground and in the atmosphere on the Earth. On Pluto, methane may be primordial, inherited from the solar nebula from which the solar system formed 4.5 billion years ago.
